VALVE.

Specification of Letters Patent. Patented Dem-13, 1910.

pplication led June 26, 1909. Serial No. 504,485.

easily operated, and which isso guided that it will not bind or become locked in the valve casing; and with these objects in view, the invention consists 1n the novel construc- ,tion and arrangement of parts set forth in detail hereinafter and claimed.

The invention is illustrated in the accompanying drawing, in which,

Figure 1 is an elevation, Fig. 2 is a central longitudinal section, Fig. Is' a ytransverse section on the line 8 3 of Fig. 2.

Referring more particularly to the drawings, 5 denotes the casing of the valve having `a side opening 6 which is the inlet. At one of its ends, the casing screwsinto the delivery pipe 7, and its opposite end is closed by a' screw cap 8. Adjacent to its outlet end, thewall of the valve casing is provided with an annular valveseat 9, v

The valve proper is a composite structure comprising a plug 10 engageable at one of i its ends with the seat 9,'said endl being beveled to make a good fit. The plug is prefer'- ably of rubber, and is held'between a guide 11 working in the valve seat opening, 'and a disk 12. The guide has wings 13 whlch have a working fit in the valve seat opening.- The guide also has the central openin 14 which is counterbored and screw threa ed at that end which vis contiguous to the plug 10. In the counterbore is screwed a tubular stem 15 which also extends through central openings made in the plug 10 and disk 12. The stem is threaded exteriorly throughout its entire length, and adjacent to the disk 12, it carries a dlsk 16 which is adapted to screw vagainst the disk 12, whereby the latter and the valvev plug 10 will be rigidly held on the stem 1.5, the valve plug being clamped between the guide-11 and the disk 12; That face of the disk 12 which is contiguous to the valve plug basan annular marginal flange 17, within which the rediiced contiguous end of the valve plug lits, and which flangeA assists to hold said valve plug in lplace. On the back of the disk 16 are radiallyextending wings 1.8.

The stem 15 carries` a plunger 19 which fits loosely in ,that end of .the valve casing lwhich is closed by the cap 8. The stem 15 extends through the plunger, the latter be- Ing screwed thereon, and at the back of the plunger the bore of the stem terminates ina Valve Seat which is engageable by a valve 20, carried by a stem 21 mounted loosely in the bore of the stem 15.m` This valve is a rubber plug suitably shaped at one end to lit 'the valve Seat, and held on the-stem 21 between a shoulder 22 thereon, and a cupped washer 28.\ The shoulder is formed by reducing the stem and -this reducedend is screw threaded to receive a nut washer 23 for clamping the same against the 2% engageable with the plug 20 whereby the latter is securely held on the stem 21 against the shoulder 22. At the base of the nut 24 is an outstanding flange 25 which is engaged by one end of a coiled spring seating at its other end in an axial recess 27 formed in the cap 8,.saidv spring serving to hold the plug 20 to its seat. The stem 21 projects a suitable distance beyond the guide wings 13 so that it may be e engaged by a trip 28 mounted on a shaft 29 tted to turn in the delivery pipe 7, the shaft being operated in the same manner as my former patent heretofore referred to.

The plungerv 19 fits sufliciently loose in the bore of thevalve 2O so that the water or other fluid may leak past the same into the A space behind the plunger. The plug20 pre- `vents the escape of this water when the valve 10 is closed. To open the Valve 10, the shaft 29 is swung to bring the trip 28 into engagement with theprojecting end of the stem 21,

and thus to unseat `the plug 20. The 'space behind the plunger 19 is thus vented, and the water is free to escape throughthe bore of the stem 15, So that therewill be no pressure to oppose the opening movement of the valve 10. The trip 28 1s swung until it engages the guide 11, whereupon the'valve, 10 1s 'forced off its seat, the valve being thus opened more or less according to the amount of water desired, veryT little pressure being required to open the valve. VUpon releasing thetrip 28, the valve 20 is forced to its seat by the spring 26, whereupon the pressure acting to force the plunger 19 and the Valve toward the seat 9 becomes greater than that opposing such movement, whereby the valve Having thus deseribedmy invention, whatl I claim as new and desire to protect by Letters Patent is A valve comprising a easing, an annular valve seat therein7 an externally threaded tubular stem in the casing, a' valve engageable with the aforesaid seat, said valve comprising a plug through which the tubular stem passes, a guide for the valve mounted on one end of the tubular stem, and having wings which lit in the valve seat opening, and said guide engaging one side of the valve plug, and having a counter-bored oentral opening into which the vtubular stem screws, a disk mounted on the tubular stem and engaging the other side of the valve plug, means for clamping said disk against the valve plug, said valve plug being held between the disk and the aforesaid guide, a plunger carried by the other end of the tubular stem, the bore of said stem opening behind the plunger', and forming a valve seat, a stem mounted in the bore of the tubular'stem, and passing through the central opening of the aforesaid guide, and projecting therefrom, a valve carried by the second mentioned stem, said valve engaging the second mentioned valve seat, yielding means for normally holding the last mentioned valve seated, and means engageable with the projecting end of the second mentioned stem for unseating the valve carried thereby, and

usaid means thereafter engaging the aforesaid f' guide to unseat the first mentioned valve.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses'.
